PrestaShop · upgrades, migration, bug fixes, integrations and care

A PrestaShop store that works, stays up to date and sells: upgrade to version 8 or 9, migration, bug fixes and integrations without stopping sales

Is your store stuck on an old version, did a module break after an update, or does an integration lose orders? I review the store, fix what blocks sales and upgrade it on a copy, so orders keep coming in the whole time.

Many PrestaShop stores still run on 1.7 and PHP 7.4, which has had no security fixes since 2022. Every change becomes a risk: a new module will not install, the host forces a newer PHP, and nobody knows what will break. I start with a review of modules, overrides and integrations. Then I upgrade or migrate on a copy of the store, test orders and switch over once everything works.

  • Upgrade from 1.7 to PrestaShop 8 or 9 on a copy of the store, without stopping sales
  • Fixes for errors, slow pages and modules that stopped working
  • Integrations with marketplaces, ERPs, payment providers and e-invoicing

Modules and integrations

These are what usually break after an upgrade.

  • UrgentThe marketplace integration module has no PrestaShop 8 version

    After the upgrade, marketplace orders would stop reaching the store.

    What to do: A newer module version or an integration through an order hub, tested before the switch-over.

  • Needs workThree modules unused for years, including an old payment module

    They slow down the back office and add security risk.

    What to do: Disabled and removed once it is clear nothing depends on them.

Upgrade plan

An order of work that keeps the store selling throughout.

  1. A copy of the store on a separate test server, with real products.
  2. Upgrade, new module versions and theme fixes on the copy.
  3. Tests: paid order, shipping, invoice, marketplace orders, customer account.
  4. Switch-over at a quiet hour and order checks over the following days.

Packages

We agree the scope, price and timeline in writing before I start. Paid modules and hosting are billed separately.

Case studies

What clients say

  • „We worked with Vlad on a Next.js project. He knew what he was doing from day one, didn't overcomplicate things and came up with better approaches on his own. I especially value his work on the site's performance. Everything was delivered as agreed.”

    George B. CEO, finance company

  • „We needed to build an MVP fast to test our idea in practice. Vlad helped us choose sensible solutions and focus on what we really needed for launch. We didn't try to build everything at once, yet he made sure the project could grow later without starting from scratch.”

    Alex N. Product Manager at StartupX

  • „Vlad got up to speed with our project quickly and pointed out several problems we hadn't treated as priorities. He sorted out our database and security issues. I liked that he didn't just complete tasks but clearly explained why something was worth changing and what the consequences could be.”

    Michał R. CTO at TechCorp

  • „We had an app where every bigger change was becoming a problem. Vlad helped us clean up the code, rebuild some of the older parts and introduce automated tests. Working on new features is much easier now. I also appreciate his patience in explaining technical topics to people outside the development team.”

Frequently asked questions

Is upgrading from PrestaShop 1.7 to 8 or 9 safe?

Yes, if it is done on a copy of the store. I first check modules, the theme and overrides, because those break most often. I upgrade the copy, test orders, payments and integrations, and switch the live store only when everything works.

Version 8 or straight to 9?

PrestaShop 9 came out in June 2025 and needs PHP 8.1 or newer. If your key modules already have a version for 9, going straight to 9 makes sense. If not, PrestaShop 8 is a safe intermediate step. We decide after the module review.

Will the store stop selling during the work?

No. I work on a copy and switch over at a quiet hour. Orders placed in the meantime are moved to the new version.

Does PrestaShop have a future, or should I move to another platform?

PrestaShop is actively developed: version 9 came out in 2025, and in February 2026 the platform was bought by the Polish group cyber_Folks together with Sylius. For many stores an upgrade costs less than a move. A migration makes sense when the store needs rebuilding anyway or another platform fits the way you sell better. After the review I tell you plainly which is cheaper.

Will I lose Google rankings in a migration?

You do not have to. I carry over product and category addresses, set up 301 redirects from the old ones and check in Google Search Console after the switch-over that the pages stay visible.

Can you fix a store you did not build?

Yes, that is common. I start with a review of code, modules and access, so I quickly see what the previous developer did. Afterwards I leave documentation, so the store does not depend on one person.

How much does it cost?

It depends on the store version, the number of modules and integrations. After the review you get the scope, price and timeline in writing before we start. Paid modules and hosting are billed separately.
